In Round 1 in the Headbanger Region, we've got Black Sabbath's eponymous debut battling Mercyful Fate's Melissa!

Black Sabbath gave birth to heavy metal when they released their self-titled debut in 1970. Armed with the ominous, devilish title track and immortal cuts like "N.I.B." and "The Wizard," the Birmingham quartet demonstrated a new sound that was nightmarishly heavy, hinging on Tony Iommi's riffing might and Ozzy Osbourne's tortured wail.

When Mercyful Fate dropped Melissa in 1983, they instantly became one of the most frightening acts in metal thanks to King Diamond's glass-shattering falsetto that still remains mostly unattempted by almost every metal singer in existence. Add in his overtly Satanic themes and the band's dynamic compositions taking cues from early Judas Priest and early Iron Maiden, Fate's worked felt like a natural progression of the feelings conjured by Sabbath in the previous decade, making this one great matchup!
